ETYLENE-GAS GENERATOR.

sPncIEIcATIoN refining part of Letters Patent Nec-16,731, dated April s,1906. Application filed November 12, 1898. Serial No. 696,267. v(Nomodel.)

. To all whom, it nea/y concern:

Be it known that we, HENRI JOSEPH AZARIE GIROUX and NARCISSE AzA GIEOUX,subjects of Her Majesty-the Queen of Great Britain, residing atCharlesbourg, county of Quebec, Province of Quebec, Canada, haveinvented certain new and useful Improvements in Acetylene-Gas-Generating Apparatus; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to improvements in acetylene-gas-generatingapparatus.

One object of our invention is to provide a device of this character inwhich the generating-chamber and accessories are located en tirelywithin the gas-holder, thus economizing space.

A further object is to provide the gas-holder with independentcompartments, in one of which the gas is formed and from which it ispassed into a separate compartment, where it is stored until used.

A further object is to provide a valve to regulate the passage of thecarbid from the carbid-chamber, the movement of the valve beingregulated by the movement of the movable section of the gas-holder.

A further object is to provide a safety appliance whereby surplus gaswill be caused to escape to the outer atmosphere.

To these and other ends our invention consists in the improvedconstruction and combination of parts hereinafter fully described, andparticularly pointed out in the appended claims.

In the drawings, in which similar numerals of reference indicate similarparts in all of the views, Figure l is a vertical sectional view takenthrough the gas-holder, showing the interior arrangement of the same,the carbid-receptacle not being shown in section. Fig. 2 is a similarview taken at right angles to Figi, showing the parts shown in Fig. land also showing the carbid-receptacle in section, the valve and itsoperating mechanism, and the water-supply. Fig. 3 is a horizontalsectional view taken on the line 3 3 of Fig. 2. Fig. 4. is a detail viewshowing the inner downwardly-extending flange formed on the movablesection of the gas-holder and showing the openings for the passage ofthe gas from 4the holder when a surplus amount of gas has been formed.Fig. 5 is a detail View of the valve.

Among the many acetylene-gas machines now in use there are to be foundmany varying systems, in most of which are to be found a great varietyof separable chambers, &c. In all of these it is required that aconsiderable space be provided for the working of the apparatus and alsothat a number of separate constructions be formed, each of whichrequires a maximum amount of manufactured work. Reference is madeparticularly to the forming of independent gas-holding andvgas-generating machines. It is our purpose to minimize the cost ofconstruction of these parts and also the space required to operate them,and to accomplish this we place the gas-generator within the gas-holderin the manner hereinafter described, thus inclosing all the operatingparts within the outer telescoping gas-holder and confining allliability of the leakage o f gas within the holder, which is kept sealedfrom the outer and surrounding atmosphere. p

In the drawings, l designates the gas-holder, comprising the outerstationary section 2 and the inner telescoping section 3, arranged inthe usual form with a provision for the usual water seal between them.The section 2 has its bottom arranged in the form of an invertedcone, asat 4, the apex of which is provided with an opening 5, as best shown inFig. 2, to allow of a ready cleansing of the generating-chamber 6.

As shown in Figs. l and 2, the section 2 is divided into compartmentsIby means of the angularly -inclined port-ion 7 and itsupwardly-extending flange 8, the portion 7 being secured to the casing 2at a suitable point above the bottom 4, the compartment within theportion 7 forming the generating-chamber 6, while the annularcompartment formed on the outer side of the portion 7 andl the liange 8isintended to receive the water forming the water seal between theVarious parts of the apparatus.

ICO

what less diameter than said flange, is a cy- Ido carbid-receptacle andits operating parts.

The diaphragm is provided with an opening 12, which leads to the lowerend of the carbid-receptacle 13, which latter is located within andconnected to the cylindrical portion 9. The top of the portion 9 isclosed, practically hermetieally, by a suitable diaphragm l1, the spaceinclosed by the portion 9 and diaphragms 11 11 forming a closedcompartment 19 for the reception of the operative parts hereinafterdescribed. The carbid-reeeptacle is mounted on suitable supports 14,said supports being provided with suitable slides 15, on which ismounted the sliding valve 16, (best shown in Fig. 5,) said valve beingadapted to close the outlet-opening 17 of the carbid-l'eceptacle 13.

It will be apparent from the foregoing construction that when a quantityof water is placed within the generating-chamber (i, by meanshereinafter described, and the valve 1G be opened the carbid within thereceptacle 13 will pass downward through the openings 17 12 into thewater, whereupon gas will be formed and pass out of thegenerating-chamber through the perforations 10 into the annular space18, formed between the flange 8 and the cylindrical portion 9, and asthe space 18 extends the entire length of the ilange S, having noclosing means at its upper and lower ends, the gas will also passdirectly from the generating-chamber into said space and be carriedupward into the gas-holding compartment 19.

The inner section 3 has its outer downwardly-extending flange 2O ofsufficient length to pass within the water seal formed without theflange S and pass downward close to the upper side of the inclinedportion when said section is in its lowermost position. Connected to theunder side of' the top 21 of the section 3 within the ilange 2O are twosemicircular downwardly-extending flanges 22 22, said flanges extendingdownward to within a short distance of the lower end of the flange 20,the space between the flange 2O and the flanges 22 forming a compartment23, within each of which is located the vertical pipe 2t, extendingdownwardly through the inclined portion 7 and bottom 4 into asuitableoutletpipe having a connection with a suitable point, such as a sewer,rbc. The flanges 22 are provided near their lower ends with a number ofopenings 25, which normally remain below the level of the water seal andare only brought into action when the section 3 of the holder has beenraised a sufiicient distance bythe excessive formation of gas to allowthe openings 25 to pass above the level of the water seal, when the gasin the gasholder will pass outward through said openings 25 into thecompartments 23 and outward through the pipe 24.- away from thegenerator, thus forminga safety device, the passage of the gas throughthe openings 25 relieving the pressure of the holding-compartment 19,allowing the section 3 to move downward, and thus automatically closethe openings 25 by passing them below the level of the water seal.Suitable weights 2G are connected to the interior of the flange 2O andserve to form a counterbalance for the pressure developed by the gas.

The valve 1G is adapted to be moved into and out of position below theopening 17 of the carbid-receptacle 13, and as this must be accomplishedautomatically we have provided an arrangement of parts whereby themovement of the section 3 will cause a corresponding movement on thepartof the valve, and thus open or close it, as is necessary in theautomatic working ot the machine. To give this automatic movement to thevalve 1G, we provide a lever 27, pivotally connected to a link 28,pivotally mounted in bearings formed on the outer surface of the flange8, said lever 27 extending inwardly to a point directly beneath thecenter of the top 21, and at its inner end is pivotally connected to theupper end of a vertically-sliding rod or piston 29, mounted within acylindrical casing 30, connected to the carbid-receptacle 13. To thelower end of the rod or piston 29 is secured one end of an arm or lever31, connected at its opposite end by means of a link 3i" to a stud orsupport 31C, secured to the walls of the chamber 19". AA bell-cranklever 31l1 is pivotally mounted in a bracket or support 31e below thesupport 31C, said bell-crank lever being connected through the medium ofa connecting-bar 3U to the arm or lever 31 intermediate the ends of thelatter, the opposite end of said bell-crank lever being connected bymeans ofthe connecting-rod 31 to the valve 1G. It will be readily seenthat with these parts in the positions as shown in Fig. 2 of thedrawings the valve 16 will beheld in a position where the opening 17will be closed until the section 3 begins its downward movement byreason of the use ot the gas within the compartment 19 and that whensuch movement begins the rod or piston 29 will be caused to movedownward vertically against the action ofi a spring 32, mounted on saidrod or piston within the cylinder 30, and by such movement and theconnection with the arms and levers cause the reci proeatin gconnecting-rod 31 to be moved, causing the valve 16 to be graduallydrawn away from the opening 17, thus allowing of the escape of thecarbid from the receptacle and causing new gas to be formed. As the newgas is formed the` sce- IOO IIO

' 1G to resume its tion 3 will be caused to move upwardly, whereupon thespring 32 will force the rod or piston 29 upwardly and gradually causethe valve position to close the opening 17. 33 designates a rodpivotally mounted on the lever 27 and extending downward into thecarbid-receptacle within a short distance of the opening 17, the lowerend of the rod being held in position by means of a suitable bearing 34,located on the inner side of the receptacle. When the section 3 movesdownwardly, the rod or piston 29, necessarily moving in a verticalposition, will cause the link 28 to move outwardly to compensate for thelength of the lever 27, this movement of the link 28 and the lever 27causing the rod 33 to be moved downwardly and at the same time have itsupper end moved outwardly to bring it into a direct alinement with theopening 17, this rod 33 serving as a plunger to force the carbid throughthe opening 17 in an obvious manner.

The top 21 is provided with a suitable removable air-tight plug 35,ylocated at a point directly above the opening 36, formed in thecarbid-receptacle, and serves to allow of the introducing of carbid tothe carbid-receptacle, a funnel or other suitable means being providedfor the purpose of allowing it to pass within the receptacle in anexpeditious manner.

Water is supplied automatically to the generating-chamber by means ofthe pipe 37, arranged on the outer side of the section 2, as shown inFig. 2, the upper end of the,pipe being arranged to have its opening ata point below the level of the water contained within the reservoir 38,which is kept supplied in any suitable manner, the lower end of the pipe37 opening into the generating-chamber, a suitable trapor siphon 39being arranged within said pipe near its lowerend to prevent any leakageof gas through the water-feed pipe.

The section 3 is guided in its movements by means of the uprights 40,secured to the side of the section 2, and held in position by means ofsuitable supports 4l 42, arranged on said section, suitable guides 43,secured to the section 3, serving to hold the said section 3 in itscentral position. The upper ends of said uprights 40 are connected by asuitable cross-bar 44, as best shown in Fig. 1.

It will be readily understood that after the gas has been formed in thegenerating-chamber, as hereinbefore set forth, it will pass through theopenings 10 or directly into the annular space 18, passing through thelatter into the gas-holdin g chamber or compartment 19, from where itwill be passed through the outlet-pipe into the house-supply pipes.Should a surplusage of gas be formed, it will cause the section 3 torise a sufficient distance to expose the openings 25 above the level ofthe water seal, and thus allow the gas to escape from thegenerating-chamber and the compartment 19 into the compartment 23,andthence to the outer atmosphere, as described.

As there is a continuous pressure formed within the compartment 19 andthe generating-chamber, it will be apparent that should the plug 35 beremoved the entire section 3 would be caused tovdrop downward and allowof the escape of the gas from the compartment 19. In order that this maybe prevented and the section 3 be held in a stationary position, we haveprovided a suitable rod 46, having its lower end formed with a hook 47,which is adaptedto be placed within a suitable eye 48, secured to t-hetop 21, the rod 46 being connected to asuitable pivotally-mounted strap49, connected to a lever 50, secured to the cross-bar 44, the free endof the lever 50 being connected by means of the link 51 with a plug 52,secu red within said cross-bar, as best shown in Fig. 1. When theapparatus is in operation, the hook 47 will be free from engagement withthe eye 48, allowing the section 3 to have a free movement, the hookbeing used only when the carbid-receptacle is being filled.

The advantages of this construction are thought to be obvious, and as afew of them have heretofore been set forth it is not thought necessaryto reiterate them.

Minor changes in the form and proportion of the parts forming ourconstruction may be made, and. it is to be understood that we do notlimit ourselves to the precise construction and combination of parts asshown and described, but reserve the right to use any and allmodifications of the said construction in so far as said modications andchanges may fall within the spirit and scope of our invention, asclearly set forthin the appended claims.

By forming the portion 9 with a closed top practically hermeticallysealed, as hereinbefore set forth, the entire operating mechanism islocated within a compartment to which the gas has no entrance, so thatthe parts upon which dependence must be placed for the proper feeding ofthe carbid will be kept free from any liability of becoming subjected tothe action of dampness, which may be found in apparatus of thischaracter when not provided with drying means. In addition to this, thecarbid-receptacle being in an entirely separate portion of the mechanismand none of the operating parts, with the exception of the plunger 33,having any communication with the receptacle, there is absolutely noliability of the parts becoming cloggcdin any manner.

Having thus described our invention, what we claim as new is 1. Anacetylene-gas-generating apparatus, comprising a gas-holder; agenerating-chamber formed within said holder; a gas receiving andretaining compartment located above and having operative connection withsaid chamber; a closed chamber formed within IOO IIO
